CD49d is a 150kD glycoprotein, also known as a4 integrin or VLA-4 a chain. It is a member of the integrin family, expressed on T and B cells, monocytes, eosinophils, basophils, mast cells, thymocytes, NK cells, and dendritic cells. CD49d is a heterodimer expressed with either of two b chains, b1 (CD29) or b7, to form the VLA-4 (integrin a4b1) or LPAM-1 (integrin a4b7) complexes. CD49d plays a critical role in both adhesion and T cell costimulation. The primary ligands for CD49d are VCAM-1, MAdCAM-1, and fibronectin. This antibody has been shown to partially block CD49d mediated interactions and, in combination with C2404-40B antibody, completely blocks VCAM-1 binding to VLA-4.
